CAR ROOF.

Application filed April 26, 1924. Serial No. 769,245.

This invention relates in general to freight far roofs and more particularly to improvements in construction of the all-steel type of such roofs. *Objects of the invention are the provision of a car roof construction, the component parts of which. are comparatively easy to manufacture at reasonable cost; the provision of a construction in which the roof sheets are held down on the car framing by relatively few parts, which parts are enclosed by a seam cap held in place without excessive strain which might cause lealrages; the provision of a construction which will be exceedingly strong and durable and have upstanding side seams insuring against ingress of water, the provision of a construction which may be subject to ventilation, and such other objects and advantages of the invention as may be found to obtain in the structure hereinafter set forth and claimed.

In the accompanying drawings forming a part of this specification, and showing, for purposes of exempliication, a preferred form and manner in which the invention may be embodied and practiced, but without limitingl the claimed invention specifically to such illustrative instance or instances:

Figure 1 is a top plan view of a portion of a car roof embodying the invention, parts being broken away for better illustration.

Fig. 2 is a side elevational view of a portion of Fig. 1.

Fig. 3 is a vertical sectional view taken substantially on the line 3--3 of Fig. 1.

Fig. 4; is a detailed vertical sectional view taken on the line l---of Fig. 1.

Fig. 5 is a detailed vertical cross-section taken substantially on the line 5 5 of Fig. 1.

Fig. G is a detailed vertical cross-section taken substantially on the line 6-6 of Fig. 1.

Fig. 7 is a detailed horizontal sectional view taken substantially on the line 7-7 of Fig. 5.V

Fig. 8 is a top plan view of a part of a seam cap at the eaves of the roof.

Fig. 9 is a vetrical` cross-section showing a manner of securing the running board saddle on the roof.

Referring to the drawings, 10 indicates the metallic side plates that extend longitudinally of the car, andare of the Z-bar type having a horizontal web 11, a depending flange 12 and an upper vertically extendingk flange 13. The side plates are spaced apart laterally and are connected by carlines 14 having a web 15 and upwardly directed Outwardly diverging sides 16 that terminate in laterally extending flanges 17. The sides 1 6 and web 15 define a channel or trough V18, the web 15 increasing in width towards the side plates 10 as the diverging sides 16 decrease in depth and the upper ends of the diverging sides 16 being substantially equidistant throughout the length of the channel.

At each end the carline'terminates in a depending flange 19 riveted to the vertical flange 13 of the side plates. Upright members or links 2O are positioned in the channels 18 and are secured therein by bolts 21 passing through to the sides 16 of' the carlines at 22. At its upper end the link 20 is apertured to provide an eye 22 for the reception of a bolt 43. Metallic roof sheets 23 extend` across the car from side plate to side plate and terminate there in depending flanges 24 riveted at 25 'to the side plates. The sides of said roof sheets rest upon the lateral flanges 17 of the carlines 14 and said sides terminate in upwardly directed flanges 26 extending over the channelv or trough of the carline longitudinally thereof. The adjacent flanges 26' of adjacent roof sheet sections 23 are in metall to metal contact but at certain spaced intervals the sides ofy the sheets and their flanges 26 are offset as at 27 to provide openings 28 into which the upper ends of the links 2() extend, the offset portions of the flanges 26 being provided with apertures 29 that register with the aperture or eye 22 of the link 2O enclosed in the space provided by said odset 27.- At each eaves end' the flanges 26 are coped at 29, as shown in dotted lines in Figure 8 to clear the rivet that secures the carline to the. side plate and to provide a vent to the atmosphere for ventilation.. f

Saddles 31, cast as a unit, are provided over the offsets 27, said saddles having a top supporting surface` portion 32 and depending roof sheet holding down portions 33 engaging the body of adjacent roof sheets opposite the offsets 27 and said saddles also hav-V ing oppositely disposed pairs of extensions 341 that lit against the flanges 2G of the roof sheets and are spaced from each other by said flanges. `he saddle is cast soas to leave a cavity into which the ott'set QT entends, said cavity being)` oit such sir/.e as to leave a little spare 3G betvveen the saddle and the oll'set 2T. The holding; down portions or' said saddles are provided with apertures that register with the apertures in the ol'l'set pon tions ot the tlanges 2G and the eye in the head ot the .link ll therein. These saddles are spared apart on the earline7 in the present instance, one each on opp "e sides ot the ridire and one eaeli between the side plates and the ridire saddle. 'the extensions 31.1-, ivhen arranged in place are riveted together and to the flanges tl'ierebetvveen by rivets 3T. it the eaves ends of the sheets ther flanges 2G are ent anni' :it Sti to allow the seam cap to tit down to the side plates. 'lfhe seani caps 3l) are ot' inv/ered eliannel shape. Their sides terminate lateral tlanges 39, and their eaves ends terminate in depending thing/'es lil that are riveted to the side plates and the depending4 liang'es ot the root' -sheet sections, by rivets lil said flanges 4l() being` pressed ont at ll opposite the Coping: :29' to provide a vent.

The senin caps 3l) ara supported inter-rneill diate their eaves ends by; the Saddl the top ll ol the senin cap r stia/f on the ilpportingI surtaees 32 ol'; the eubiaeent and the sides l2 resting` against t the holding down portions Il?, ot tin sain The seani caps are rigidly7 supported on said saddles` by bolts etj that pass through the sides l2 of said seani caps l) and t onerii the apertures in the hold 3S ot the saddles, the :ipe lares ,in the oliset,r` 27 and the eve 22 in the link 30. there bolts -ll are riveted di'nvn on the outer sin faces of the sides ot the :c ain caps as at In order to support and hold the running board saddles llo, tivo holding nieinbers -l-l are provided for eaeh saddle, each olf aid holdinginenibers eonsistinghj;` ot a single piece ot' niet-al bent upon itseljt' at ed" to '.erire said n'ieinber to said saddle and having` a portion bent horizontally at 1l-tl to support the saddle and also to rest upon the top ot the :I-seani ap 30 and the portion itl then lr-eing hunt downwardly at 52 against 'the side et the seani eap. The other portion Lit) t aid ineni ber ol i t at ll and then eontiinies` dfiuvn at 51 against the other sine ol" the seein rap. These. portions and :"2 are i'feenred in place by the bolt ll that p: s through the seam ear, inside saddle and olffets there-- under at the ridge.

From the l'oregoin5 53I it will be noted that the senin caps are ieeiil'ely .s :i'ipiiorted h v the saddles and that the ldles hv reason ot the bolt 43 and linl; Q0 hold t ie reo t srieels dinvn i "line and that rerured roede-ee ni the parts enables the saddles to funetn as supports tor the seani caps and as holding down n'ieans :lor the rooting seetions. ln order to provide tor ventilation the sides ot the earlines are apertured as indiealed at To azsenilile the roof above deseribed, the eariines are iii-st feeured to the side plates and the linlcs Si() then secured on the earlines. the root sheets are thou assembled over the earline';` se 'that the respective oltsets register and the upper ends ot' the links are enclosed by the rei-responding olisets. Then the sadare arranrgelfl over the oll'sets so that the ertures in the holding` down portions and e apertures in the oltsets 2i are in registration. 'lheu the extensions 3ft are connected by rivets 3T to the llanges 2() of the l sl Then the seani caps 30 are aranged orer the saddles to cover adjacent les ot adjacent rooting sections and the ;olts -lil are then passed through the regiseringgv apertures in the seani cap, holding doen portions et the saddle, the apertures i the ollsets 22' and the eye 22 in the link ,fitter the holt a3 is infaerted each end is riveted down on the sides of the seams and the eaves tianges ot the root sheets and seam rap are then riveted to the side plates. At the ridge the running board saddle supportnieiuber are applied before the bolts 43 are passed through the aperture and the bolt 'i then riveted down ou the portions 5l and nl thereofi llnnning boards seeured to the wooden running; hoard saddles extend longitudinally of the root as usual.
